Polycystic ovary syndrome (PCOS) is a relatively common condition that affects how a woman’s ovaries work and how her eggs are released. Irregular periods are a symptom of PCOS and can indicate the reason for infertility.
Bourn Hall hosted a webinar, ‘PCOS and Fertility’, to talk about this subject and answer some of the most frequently asked questions. We include below some of the information we shared and also a video of the PCOS Q&A session from the webinar.
Symptoms of PCOS
Women with PCOS often have a hormone imbalance, particularly abnormal levels of insulin – the hormone that controls sugar levels in the body – and higher levels of testosterone, the ‘male’ hormone.
This can cause the following:
- Irregular periods – ovaries do not release eggs regularly (ovulation)
- Excess body hair and acne
- Polycystic ovaries – where the follicles fill with fluid
Women with PCOS often find it difficult to maintain a healthy Body Mass Index (BMI), which in turn can have an impact on fertility, because being overweight or underweight affects the amount of insulin your body produces.
PCOS and egg production
A human female is born with all the eggs she will ever have and they are contained in small follicles in the ovaries. This is called the ovarian reserve (egg store).
After puberty, follicles are ‘recruited’ from this ovarian reserve and then undergo about three months of growth and development before ovulation (egg release). At the start of each month, there are around 15-20 follicles which have made it to the final stage of this process.
Under normal circumstances, only one of these follicles will become dominant and be exactly the right size, at the right time, to finally release its egg. One egg will be released each month, and if it isn’t fertilised ovulation will be followed by a period.
However for women with PCOS there is a hormone imbalance so lots of follicles develop and the eggs are not released. Instead the lining of the uterus thickens until eventually it is lost in a bleed.
A regular menstrual cycle is therefore a good indication that you are ovulating.
How PCOS impacts fertility
Bourn Hall has been offering fertility treatment for 40 years and is the world’s first IVF clinic. It was set up by the IVF pioneers Steptoe, Edwards and Purdy.
When they started their research very little was known about fertility health or about the impact of the hormones on ovaries. Much of this knowledge and the medication to treat infertility has been developed here at Bourn Hall.
Dr Arpita Ray, Regional Lead Clinician at Bourn Hall, and Angela Attwood, Nutritional Therapist from Love Nutrition, discuss the impact of PCOS on fertility and how good nutrition can improve fertility.

PCOS and how nutrition can help
Angela Attwood, Nutritional Therapist, Love Nutrition
Angela was first introduced to nutritional therapy as a patient, to help her recovery from cancer treatment. Having seen the benefits she studied to become qualified and has built up a practice helping people struggling with their hormonal health, which includes fertility, digestion and weight management.
